Imagine what the Ukes can do with a lot of these targeting refineries and weapons manufacturing way inside Russia and over all the Russian supply lines to their invasion force!
“weapons manufacturing”
‘Cottages’ can be built in conifer forests.
A drone would if lucky take out a machine, a ‘cottage’ and a few parts.
It might just take out a Potemkin Village ‘cottage’ shell.
“refineries”
Russian cities probably have good public transport.
The harvest is probably mainly complete. Winter is coming soon.
“targeting refineries”
The Russians are surely going to making all the necessary spare parts. They could be put on railcars in hours that could travel over 1,000 miles in a day.
Critical parts of refineries could be protected by vertical steel I-beam fences.
Rail bridges are more vulnerable.
